Normal daily activities (such as taking showers and baths, washing and drying clothes, cooking and boiling kettles) produce warm air containing a large amount of water vapour.
If there is a strong enough wind blowing from the sea the warm air above the land is cooled, releasing the water vapour as droplets.
